SHOVEL FOR PLOWS.

SPECIFICATION forming part of Letters Patent No. 410,381, dated September 3, 1889.

Application filed June 14, 1889. Serial No. 314,241. (No model.)

To all whom it may concern:

Be it known that I, VILLIAM L. SEXTON, of Scranton City, in the county of Greene and State of Iowa, have invented a new and useful Improvement in Shovels for Plows, of which the following is a full, clear, and exact descript-ion.

My invention consists in a transversely-divided shovel for plows or cultivators, pro- IO vided with a hinge-connection of the divided portions, which are held in proper relation with each other by a break-pin attachment, substantially as hereinafter described, and

. pointed out in the claims, whereby in case of I 5 the point of the shovel striking an obstruction such pointor lower portion will be released by the rupture of the break-pin and so be allowed to drop or swing back, thereby preventing the breaking of the shovel. Such construction also provides for a saving of metal in the manufacture of plow-shovels.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the views.

Figure 1 represents a frbnt view of a shovel embodying my invention and as attached to the leg or standard of 'a plow or cultivator, which is represented as broken away. Fig. 2

is a rear view of the same. Fig. 3 is avertical section of the same upon the irregular line a; a: in Fig. 1. Fig. -l is a transverse section upon the line 1 y in Fig. l; and Figs. 5 and 6 are diagrams in illustration of the manufacture 3 5 of the shovel.

Referring, in the first instance, to the first four figures of the drawings, A indicates the upper or body portion of the shovel and B the point or lower portion thereof, 1) indicating the transverse division of the shovel or blade.

Upon the back of the portion Bis a casting C, which is provided with two lugs or ears 0 c, and upon the back of the portion A is another casting D, provided with an ear (1, that enters in between the ears 0 c, to form a hinge-joint having its axis in transverse relation with the shovel below the division I) of the two parts AB and fitted with a hinge-pin e. These castings O and D are respectively secured to the parts A and B by rivets f, or otherwise, and

the upper body part A, with its attached cast ing D, is further secured to the leg or standard E of the plow or cultivator, as by a bolt g, provided with a nut, or otherwise. Said castings O and D, in addition to providing for the hinging of the two shovel-blade sections together, as described, constitute stiifening or re-enforcing pieces on the back of said sections and overlap one another where meeting-that is,be1ow the division I) and between it and the hinge. The overlapping portion of the one re-enforcing or hinge piece D of the body part A of the shovel-blade has a slot h in it, through which an ear 2' upon the underlapping portion of the re-enforcing or 6 hinge piece 0 passes and projects, and is perforated to receive through it awooden pin it. This serves to lock the two hinged shovel-sections A and B and to hold them in position.

From this description it will be seen that if when using the plow the point should strike an obstruction liable to damage or break the shovel, the wooden pin 70, which is a break as well as a locking pin, would give way and allow the lower part B of the shovel to be thrown or swung backward from the hinge-pin e as a center of motion, as shown by dot-ted lines in Fig. 3, and so save the shovel from breaking. The construction of the shovel-blade, too, in independent sections, as described, will be So much more economical than making them in one piece, as usual. To illustrate this reference will now be made to Figs. 5 and 0 of the drawingsl Thus, to make the shovel in a single piece, it will take to make two shovels, say 22 inches in length from a slab of steel, A A in Fig. 5 indicating the-two shovels and S S the waste metal which is left in producing the point ends of the shovels; but by making the shovel or shovel-blade in two parts, as de- 0 scribed, and cutting the slab of steel, as represented in Fig. 6, to make two shovels-that is, two body parts A A and two point parts 13 Bbut a small portion of waste metal S will be left, and a saving of steel will be effected equal to half of another shovel, or thereabont, so that in cutting out a set of four shovels enough of steel will be saved to make an extra shovel, which will be equivalent to a saving of about one-fifth of the said sections and constructed to form ahinge at the back of the lower one B of said sections, having its axis in transverse relation with the length of the shovel, also a locking attachment above the hinge adapted to receive a transverse break-pin through it, substantially as shown and described.
